Gas Mask

Gas masks are a kind of filtering respiratory protection products, as personal protection equipment, used to provide effective protection to the respiratory organs, eyes and facial skin of personnel. It is mainly composed of filter element, hood, eye window, exhalation call device and headband. The mask is directly connected to the canister or cartridge for use, known as the direct-connection type; or the air conduit is connected to the canister and cartridge for use, known as the catheter type.
Gas mask is the use of mask and the human face around the formation of a close, so that the eyes, nose, mouth and face and the surrounding poisonous environment isolation, and at the same time rely on the canister adsorbent adsorption, absorption, catalytic effect and the filter layer of the filtering effect of the outside world will be purified poisoned air, to provide the personnel to breathe with clean air. It can effectively protect the face, eyes and respiratory tract of the wearer from toxic agents, biological warfare agents and radioactive dust. The gas mask can be used in various types of canisters according to the protection requirements, applied in chemical industry, warehouses, scientific research, all kinds of poisonous and harmful operating environment, and can be used by personnel in different fields such as industry, agriculture, medical team, scientific research, etc., and can also be used in the army, police and civil defence.
